What does «light» and «heavy» rain mean?

On the bottom of the frontpage you can see information about precipitation for the current hour. Either «No precipitation», «chance of precipitation», «light rain», «rain» or «heavy rain».

But how many millimetres rain (or snow) is classified as «heavy»? 

All values are minimum/maximum estimated rain, snow or sleet for one hour: 

Light rain: At least 0.1 mm/h

Rain: 0.5-1 mm/h

Heavy rain: 1 mm/h and up
